背景技术Background technique
铝铂涂层具有优异的抗高温氧化性能，可以将高温合金的耐热温度进一步提高300～400℃，常作为抗氧化涂层或热障涂层的粘结层应用于航空航天、船舶、能源和动力汽车等领域。目前，铝铂涂层的制备方法主要分为四步：首先在金属基体上电镀一厚度为5-10μm的纯Pt层；其次，试样在真空下进行扩散热处理一般被叫做预扩散，在此过程中会使Pt层和基体产生一定量的互相扩散；第三步是在试样表面渗入铝层，渗铝过程可以采用多种方法，比如料浆法、化学气相沉积法或气相法；最后，经过热处理使得基体恢复本来的机械性能。该方法的工艺流程较长且比较复杂，成本较高。电沉积法是一种制备合金涂层的有效方法，可以通过调节电化学参数来控制产物的组成、结构、形貌等，具有流程短、设备简单、操作简便、成本低廉等优点。Aluminum-platinum coating has excellent high temperature oxidation resistance, which can further increase the heat resistance temperature of superalloy by 300-400℃. and power vehicles. At present, the preparation method of aluminum platinum coating is mainly divided into four steps: first, a pure Pt layer with a thickness of 5-10 μm is electroplated on the metal substrate; secondly, the diffusion heat treatment of the sample under vacuum is generally called pre-diffusion. During the process, a certain amount of mutual diffusion will occur between the Pt layer and the substrate; the third step is to infiltrate the aluminum layer on the surface of the sample. Various methods can be used in the aluminizing process, such as slurry method, chemical vapor deposition method or vapor phase method; finally , After heat treatment, the matrix restores its original mechanical properties. The technological process of this method is relatively long and complicated, and the cost is relatively high. Electrodeposition is an effective method for preparing alloy coatings. The composition, structure, and morphology of the product can be controlled by adjusting electrochemical parameters. It has the advantages of short process, simple equipment, simple operation, and low cost.
铝、镁等活泼金属由于其还原电位负于氢的还原电位，不能在水溶液中利用电化学还原的方法制备得到纯金属及其合金。而离子液体是一种比较理想的电解液替代者。离子液体一般由有机阳离子和无机或有机阴离子构成，在室温或接近室温下呈现液态。离子液体具有蒸气压低、离子导电性好、电化学窗口宽等优点，特别是在金属电沉积方面具有独特的优势，被认为是一种绿色节能的电解质。Since the reduction potential of active metals such as aluminum and magnesium is negative than that of hydrogen, pure metals and their alloys cannot be prepared by electrochemical reduction in aqueous solution. The ionic liquid is an ideal electrolyte substitute. Ionic liquids are generally composed of organic cations and inorganic or organic anions, and are liquid at or near room temperature. Ionic liquids have the advantages of low vapor pressure, good ionic conductivity, and wide electrochemical window, especially in metal electrodeposition, and are considered to be a green and energy-saving electrolyte.

The temperature of the electrolyte was 90° C., the potential applied to the working electrode was 1.6 V during the constant-potential electrodeposition, and the electrodeposition time was 1 h.
本实施例制备的Al-Pt合金，采用EDS检测本例制备的Al-Pt合金组成为55.62％Al-44.38％Pt。The composition of the Al-Pt alloy prepared in this example is 55.62%Al-44.38%Pt by using EDS to detect the composition of the Al-Pt alloy prepared in this example.
